MATLAB Online에서 열기 Hi, I have a 3 equation 3 variable system which I can solve in cmd window using this code: 테마복사 v1=10; v2=5; v3=4*I1; r1=6; r2=20; r3=15; r4=6; r5=10; rl=8; eqn = [0==v1-(r1*I1)-(r2*I2),0==(r2*I2)-(r3*(I1-I...
R = (4*h/(4+2*h))^(2/3); I = sqrt(0.0016); eqn = Q == k*A*R*I; solve(eqn) k = 50; A = 4*h; R = (4*h/(4+2*h))^(2/3); I = sqrt(0.0016); eqn = Q == k*A*R*I; h_sol1 = solve(eqn,'ReturnConditions',1); h = h_sol1.h parms = h_...
sol_h = dsolve(eq1,eq2,eq3,eq4,eq4,eq5,eq6); I'm can't use dsolve forsol_h.Why ? Select the China site (in Chinese or English) for best site performance. Other MathWorks country sites are not optimized for visits from your location....
syms command does not execute, even having Symbolic toolbox, and matlab gets stuck, how can I solve this problemhttps://www.mathworks.com/matlabcentral/answers/399991-syms-sym-and-mupad-functions-cause-matlab-to-freeze#answer_319490
In example, I want to do something like: syms x y z;_I do not know how to set the symbolic at command line : f=f(x,y,z); g = x * f + y * f^2 + z; jacobian( g, [x,y,z]) and the expected result will be : ...
This is how our input and output will look like in Matlab command window: Input: Output: As we can see in the output, the signal is restricted with a maximum lag of 15 as expected by us. Example #4 Let us take another example where we will use xcorr method to compute the cross-cor...
an EPS file and use the epsc command to save it in color format. In the parenthesis, we take gcf. To save a current figure, we must specify fig as gcf, then take a file name, ‘Barchart1’, and specify the format type ‘formattype’ to epsc. In the EPS file, we save a ...
I have an old version of Matlab (2008), when I try to create an ODE function and solve it, it does not work and errors appear as follows: >> syms y(t) ??? Undefined function or method 'syms' for input arguments of type 'char'. >> y(t) = dsolve(diff(y,t) == t*y) ??
